How to select an air duct cleaning company?
There are health and fitness benefits for all residents from regularly cleaning the Heating, Ventilation, Air Conditioning (HVAC) System.
Heating, ventilation, and air cooling (HVAC) systems collect mold, fungi, bacteria and many different contaminants that reduce the quality of the environment residents and visitors breathe. A dirty air duct plays a part in poor indoor air quality and affects the health of individuals the residence.
The goal of residential air duct cleaning is always to remove these contaminants from the home’s HVAC system to get the best indoor air quality.
The best way to wash an air duct and/or ventilation system is to apply a specialized, powerful vacuum which puts air duct / ventilation system under negative pressure. As the vacuum draws air through the system, products are inserted into the ducts to dislodge contaminants and debris from the interior surfaces, moving the contaminants/debris from your home’s air ducts and ventilation systems into the vacuum.
Vacuum collection alone does not clean the HVAC system. Brushes, air whips, “skipper balls” along with other tools that agitate contaminants and debris scrub the surfaces inside the air duct system and propels contaminants and debris into the vacuum collection device(s).
Anti-microbial chemical sanitizers are applied to the inside top of the air ducts to regulate microbial contamination…but…before sanitizers are employed, the system ought to be thoroughly cleaned. All anti-microbial chemicals used has to be EPA registered to be used in HVAC systems. Ask to see the chemical’s Material Safety Data Sheet (MSDS). In case you are still concerned, call the EPA at 1-800-438-4318. There are no EPA registered anti-microbial products to use on porous system surfaces – like fiberglass surfaces.
When sanitizing air ducts you need to ensure the air duct cleaning company uses safe; effective EPA approved items that are safe for individuals, pets, as well as the environment. An atomizer fogs the sanitizing product through the entire ventilation system.
Allergic people, infants and elderly are particularly sensitive to the microbes that induce respiratory problems like bacteria, mildew, fungi algae and dirt mites which need a highly-effective sanitizer to eliminate odor-causing microorganisms as well contaminants associated with allergies, mildew and bacterial growth. Ensure the sanitizer is rated by the EPA being a category IV product with the lowest toxicity rating. Sanitizing air ducts means toxicity and safety safeguards that establish and make certain you will find no harmful dermal (skin), ocular (eyes), inhalation (breathing) or ingestion (swallowing) effects through the products.
There are two popular types of vacuum collection systems…those installed on trucks and trailers versus portable units. Truck/trailer mounted devices are generally more powerful than portable equipment. By contrast, portable equipment often can be brought right into a facility, locating the vacuum even closer to the ductwork. Both varieties of equipment clean to air duct industry standards. Vacuum units needs to be attached to a collection device for safe containment just before disposal. A vacuum collection device which exhausts indoors must be HEPA (high efficiency particulate arrestance) filtered.
